So here's my 2 cents...
Stop cry the blues people
Sure they ask insane prices,and they snag up all the good parts at swaps before anyone else gets to even look for it! They did all the work to find the stuff,and they should get every penny they think its worth!!
Sh#t if i had to walk two booth's over and buy something,and then bring it all the way back to my booth,I'd charge triple the actual worth just because i broke a sweat!!!
Just pay the guy the $250.00 he's asking for that date coded
ballist resistor.Hey, he might just throw in those NOS wire connector's that you'll need for it?
If you can't find it, are to lazy to look for it,or have alot of cash. Then by all means buy parts from the very first vendor you see,Never mind that inflated price! Me i'll just go to my backyard and start picking Hemi's off of my magical Hemi tree!
